Statistics for the problems solved using alg1

Given a problem consisting of \(m\) subproblems with \(Y_N^s\) given for each subproblem \(s\), we use a filtering algorithm to find \(Y_N\) (alg1).

Note that the width of objective \(i\), \(w_i = [l_i, u_i]\) should be approx. \(10000m\):

Size of \(Y_N\)

What is \(|Y_N|\) given the different methods of generating the set of nondominated points for the subproblems?

## # A tibble: 4 × 3
##   method mean_card     n
##   <chr>      <dbl> <int>
## 1 l         40915.   110

Does \(p\) have an effect?

Nondominated points classification

We classify the nondominated points into, extreme, supported non-extreme and unsupported.
